TURNTABLE EQUIPMENT FOR PAVING ANI) ANALOGOUS MACHINES.

Application filed July 8,

'Well known types ot mobile machines l'or paving with concrete, andcertain types ot cement mixers are provided with a skip for elevating abatch ot the materials to be mixed and discharging such batch into amixing drum. This skip, on the larger machines, is designed to permitdumping ot a truck load ot material into it at one operation and inorder to so dump a truck, it is necessary that it shall be turned aroundand backed to the skip. To accomplish this, a turntable is usuallyprovided to be rotated by hand atter a truck has been driven torwardlyonto it. This is necessarily a slow and arduous operation, requiringseveral laborers. Moreover, this turning is dangerous to thoseperforming the operation, with the result that casualties are frequent.

Another drawback with the usual turntable is the diiticulty experiencedin moving it from one place to another, two or more teams or a tractorbeing commonly employed for this purpose. lVhen paving, to obviate thenecessity of moving the table any more than is absolutely necessary, itis usually placed on the grade quite a distance in advance ot the pavingmachine, and after each truck is turned around by means otfthe table, itis backed to the skip and dumped. Very often. the truck cannot be gotteninto proper position for dumping the entire load into the skip andexpensive loss of' time and trouble ensue.

It is to overcome such difficulties as those set. forth. that I haveprovided thu` present invention. and with this end in view. saidinvention has been so devised as to embody novel structural features andunique relations ot parts, hereinafter described and. claimed, thedescription being supplemented by the accompanying' drawings.

Figure l is a perspective view ot the turu table equipment operativelyconnected with a well known type ot paving machine. the skip ot thelatter being shown in its raised. discharge position.

Figure 2 is a perspective view illifistraling the skip in loweredposition. and in the present. disclosure ot the invention. it is thislowering ot' the skip which turns the turntable one-half revolution toreverse the truck previously driven onto it, permitting said truck todump into the skip and then drive forwardly trom the table.

rotatable portion o'l.' the turntable removed, illustrating` the mannerin which elevation ot the skip is utilized to raise the base of theturntable from the ground and place its weight upon carrying wheels,when said turntable is to bemoved from one position to another, with thepaving machine.

Figure 4 is a fragmentary top plan view.

Figure 5 is a top plan view of the central portion of the turntable baseand associated parts.

Figure 6 is a vertical longitudinal section on line 6-6 of Fig. 5.

Figure 7 is a horizontal section on line 7-7 ot Fig. 6.

Figure 8 is a detail transverse section as indicated by line 8-8 of Fig.4.

Figure 9 is a horizontal section partly in elevation showing thepreferred connecting means between the turntable equipment and thepaving machine.

In the drawings above briefly described, l0 designates a portion of awell known type ot' concrete paving machine, said machine having apivoted skip l1 at its front end which is movable from a lowered,receiving position (Fig. 2) to a raised, discharge position Fig. l),said skip when in the latter position discharging its contents into theusual drinn l2 ot the machine 10. The skip is provided with the usualraising means,

y embodying two reaches of cable 13 passing over appropriate guides 14and having suitable connection with said skip. These cables are woundupon the usual drum means (not shown) to elevate the skip, and when saidcables are allowed to pay out, the skip lowers by gravity. In thepreferred form ot my invention, I make use of the weight ot the skip,rasit lowers, to effect turning of the turntable one-halt revolution, so asto reverse a loaded truck on said table, and it will be observed that byso utilizing the weight ot the skip to reverse the position of thetruck, no added strain is placed upon any parts of the paving machinel0.

The paving machine is successively advanced along the grade, between theusual forms 15. said machine being ordinarily provided with endlesstreads 16 which travel upon said grade. The turntable equipment which Ihave devised for use in connection with this or a similar machine, isdisposed in advance ot such machine and is connected 'with it. 'sa thatthe two pregi sa ne e, angie mechanism and always maintain properoperative relation. This turntable equipment Will now be described.

A base B is provided with normally idle rollere` or Wheels 17 'which mayeither run upon the forms vl5 or upon the Agrade and may be shapedaccordingly. lllornial'lyj this)4 base B reste upon the round, butprovision is made, hereinafter described, for l"l 'no' said base free ofthe ground and enppY its Weight upon the Wheels l'] When the vturntableis to be advanced with the meohine l0.

The rotatable portion lt ot the turntable ie Supported by the base l andWhile it i it be Aof flat-topped construction, it is piedrably oframelile form and einhodieisv tivo channel-shaped tracke 18 to receivethe :Wheels oli' .a .motor truclr T. The bese -il includes twochannel-Shaped aipvil'iroaclies l) which incline to the tracks4 187iierrnitl'ii truck T to be driven forwardly onto d Atracks as will beclear trein F l. deumid- 'ingl to the present disclosure oit' theinvention, the truck is `driven onto t-beec tracle when the Skip ll israised, and provie' n is ,made for ,automatically tu fling' tl Y, tableportion R one-half revolutie-i as ,i' skip is vlowered to receive ,themare ial Ltrom the loaded truck. When the .truck ia thus turned around,its rear Wheels are positioned so that they may 'travel Arearwardly ontofixed ele vated tracks 20 which are rigidly carried by the base B, .andthe front end oi' the :ildp ie. provided With an elevated pl ti'orin `2lor other desired means, onto Wlch the rear Wheels of the truck may bebacked?, to the limit permitted by the Stop Thus, the truck may becleanly dumped into J die Skip 1 1, and the load will be dischargedcloefcr lo the ,Skip pivot ll', than im ordinarily posible. Hence, themachine may elfV `be loaded Skip With the expenditure ot' lese powerthru: is 110W commonly necessary'. Moreover. les-fi lStrain is: placednpon the cables: 'i3 and :inflociated parte.

After the truck has dumped i Fig. '2. Then, the elip ll may `be toVdiecliarc its load and provision is made whereby this elevation oil'the elrip Will not `:move the turntable portion R. rlhufi. no added loadis placedupon the machine l0. After one trucl: leaves, the entireaeeembly oit parte is 'ilnrreadineee to receive another truck, and theoperations above defined, are then repeated.

lvhen the praying?r machine l0 ie to be vadvii-need along the grade, theWheels 17 are brought into play to carry the Weight of the turntableequipment and it may here be e2;- plained that when the base B and theportion R are elevated and their Weight placed upon said Wheels li', theapproaches 19 and the reeeeee spirit o-l" or :iacrilicing any el' dieadvantages of `the invention. For illustrative purpocose one practicalwey of constructing the machina here been illust ted in thedrnwinggefiend will noiv be `ifpecideally desscribeel.

The base l includes tivo parallel longitui dina-l sills 23 Whose :lirontende tarry the approaches 19 and Whose rear ends carry the traclre 20.These faille are. .igii'lly secured to liront and reesr7 tran beninofiel which may be termed oft cliann l steel, and near tbe outer ends oitthese beams, the latter are cou nected. by inner and outer longitudinallull-ey or beanie and E2G respectively. A 'third transverse beam 27 if;preferably interposed between the beams Q-:l :inl Secured to the membersand 2G. For a purpose to appear, the ends' of the beam 27 are providedwith cable guides 2S, one pair oil guides being` disposed at each end otse id beaim.

B to rise lxeeot the crouml. pl ing its on yr the d ruin rotation ol oi ed when theiced to l" ne require@ .In lowered onto the i Seil i" are provided withradially positioned rollers 38 mounted in appropriate brackets 39, saidrollers traveling upon an' annular track 40 which is suitably secured tothe base I3. In addition to the tracks 18, the table portion Rpreferably includes three transverse bars 41, 42 and 42, the ends ofthese bars being secured to said tracks. The bar 41 is centrallypositioned and is formed with an opening through which the shaft 34passes. Thus, this shaft and associated parts constitute a central pivotabout which the turntable port-ion R rotates, so that the rollers 38need not be provided with flanges to engage the track 40 and hence agreat deal of friction is eliminated.

A large driving gear 43 is provided for the turntable portion R, saidgear being secured to said table portion in any desired manner. In thepresent showing, it is fastened by bolts or the like 44 to thetransverse bar 41, and ball bearings 45 may if desired, be interposedbetween said gear and the bolster 37, it being of course understood thatsimilar anti-friction bearings could be used at any other desired pointson the machine.

A short longitudinal bar 46 centrally disposed, is shown extendingrearwardly from the beam 27 to the rearmost of the beams24. In anydesired manner, this ,bar 46 supports an upstanding stub shaft 47 whichis disposed behind and parallel with the shaft 34. Rotat-ably mounted onthe upper portion of this stub shaft 47, directly under an appropriatebrace 48 for said shaft, is a driving pinion 49 which meshes with thegear 43. A drum 50 is rotatably mounted on the shaft 47, under thepinion 49 and a. oneway driving connection, such as a ratchet mechanism51, .is employed between said drum and pinion. This ratchet connectioncomes int-o play to drive the pinion 49 by means of the drum 50. so aslo rotate the portion R of the turntable, when said drinn is driven inone direction. The ratchet connection also permits retrograde rotationof the drum 50, without similarly rotating the 'pinion 49.

A cable reach 52 is wound in such a direction upon the drum 50, that apull upon said cable will drive said drum in table turning direction.This cable reach 52` in the present disclosure, passes around a suitablecable guide 53 on the base l5, around other guides 54 and 55 carried bythe machine 10, and is connected with the skip 11, there being someslack in said cable reach 52, when the skip is raised as in 1. Thus, bythe time the skip has lowered to such an extent as to well offset itsweight from direct downward action on the pivot 11', this slack is takenup, and the weight of the skip in descending, then pulls upon the cablereach 52, effecting rotation of the drum 5() in table-turning directionso as to effect one-half revolution of the table portion R, reversingthe position of the truck previously driven onto the tracks 18.

Any desired means, such as a brake 56, acting on a portion of the drum50, may be provided to arrest the movement of the rotatable tableportion It, and a lever 57 has been shown suitably mounted upon the baseB and connected by a cable or the like 58 with said brake 56, for thepurpose of operating the latter.

Provision is made for rewinding the cable reach 52, upon the drum 50,when the skip 1l is again raised. To accomplish this, I prefer toprovide a second cable reach 59 wound on the drum 50 in the reversedirection from that in which the reach 52 is wound. This reach 59 ispassed around a cable guide 60 on the base B and around another guide 61on an arm 62, said arm projecting forwardly from the frame of themachine 10 and being suitably braced to the latter, as indicated at 63.The upper end of the reach 59 is connected to the skip 11. Thus, cachtime the skip is raised, the cable 59 is unwound from the drum 50,causing rotation of the latter in such a direction as to rewind thecable 52 thereon, the ratchet connection 51 then coming into play topermit the idle retrograde rotation of the drum. Obviously, when theskip 11 lowers, pulls upon the cable 52 and turns the drum 50 intableturning direction, the cable 59 is re` wound upon said drum, inreadiness for further performing its function.

I have made novel provision whereby, when the paving machine 10 and theturntable equipment are to be advanced as a single. unit, the lastupward movenient of the skip 11 before such advancement is to be made,is utilized for lifting said turntable equipment free from the groundand placing its weight upon the wheels 17. The mechanisni foraccomplishing this result is shown in Figs. 6 and 7.

I have previously described themanner in which rotation of the drum 38,in one direction, would effect the desired raising of the turntableequipment, so that it may be moved upon its wheels 17. I will nowdescribe the manner in which this drum 88 is rotated in the desireddirection. In the figures just referred to, it will be observed that agear 64 is secured to the drum 33 and meshes with a pinion 65 which isrotatable and slidable upon the stub shaft 47. Co-acting clutch means 66are provided on this pinion 65 and the drum 50, so that when said ineansare engaged, the pinion 65 will be rotated, causing it to rotate thegear 64, thereby driving the drum 83 to attain the desired end.

For elevating the pinion 65 to interengage the clutch means 66, I haveoperatively connected a suitably mounted lever 67 with said pinion, andhave provided an operating cable IIO fifi

il i

(38 :tor said lever, said cable passing,- over appropriate guides (59and extending,` rearwardly to be controlled by 'the operator of themachine l0. rlhus, whenever the operator is in readiness to advance themachine and the turntable equipment, .it is only necessary to actuatethe cable 68 in the proper manner when raising the skip ll. Then, thecable 59 rotates the drum 50 and the latter, by means or theinter-engrigi-ncr clutch means (i6, drives the pinion 65. liis pinion.in turn drives the rear (il and the drum 33 is .thus rotated :to windthe cables 32. 'lhese cables pull upon the cables 3l, turninp' thecranked .ailes 29 so as to raise tl ne entire turntable assembly clearoit the ground and place its weight upon the wheels l?. Then, as theturntable assembly is connected with the machine l() .tor advancementwith the latter, the entire assemblage may be 'tor- 4wardly moved to thedesired extent.

rlhe preferred manner et connecting the turntable equipment with themachine l0, is shown most clearly .in Vlligs. l, 3 and 9. From theseviews, it will be seen that a horizontal-ly positioned, "ll-shaped trameT is inter-posed between the machine l0 and the hase B. The arms of thistrame 'i'O are pivoted on transverse axes 7l to the rear end ot the baseB, `and the arm-connecting, rear portion of said frame 70 is connectedwith the liront end of the machine l0, preferably with its front axle72. ln establishing;` this connection, l prefer to provide a transversehorizontal rod Wl spaced in liront ot the aide 72 and having rearwardlyturned ends 75 which are suitably secured to said axle. A slide T6 isprovided with rollers 77 movable along the rod 74; and by anyV desiredmeans such as a holt T8, said slide is connected lo ,the aforesaidarm-connecting portion or the trame 70.

The connections employed at the Vtrontand rear ends ot the 'trame Y0,not only permit the necessary vertical. movement. oli the turntableassembly ttor' purposes above set forth, but the slide `76, rod 74tandassociated parts, permit `slight relative movement oll the machine l0with respect to the frame TO, which. is essential, itis practicallyimpossible to advance the euml some paving machine kexactly down thecenter oli'tbe grade liilh'ile excellent results may be obtained tromthe lgeneral construction herein shown and described, it, is to heundenstood that the present disclosure is principally Yl'or illustrativepurposes, and that within the scope ol the invention as claimed,numerous variations may be made.
